Printer Self–Tests
With the exception of testing the interface between the printer and the host
computer (and the associated data cable), you do not need to send data from the
host computer to the printer to test printer operation. You can use the printer’s
built-in diagnostic tests to check many of the functions of your printer, including
print quality and overall operation. These diagnostic tests include the following:
v Printer Demonstration
Demonstrates all the functions and features available on the printer.
v Print Error Log
This test prints the contents of the printer’s internal error log.
v Ripple Print
A “sliding” alphanumeric pattern used to identify missing or malformed
characters, improper vertical alignment, or vertical compression.
v All E’s
A pattern of all uppercase letter E’s used to identify missing characters,
misplaced dots, smeared characters, improper phasing, or light/dark character
variations.
v All H’s
A pattern of all uppercase letter H’s used to detect missing characters or dots,
smeared characters, or improper phasing.
v All E’s + FF (Form Feed)
A pattern of all uppercase E’s repeated for ten lines and followed by a form feed
to the next page top-of-form, used to identify paper motion or feeding problems,
such as paper path obstruction or improper forms.
v Underlines
An underline pattern useful for identifying hammer bank misalignment.
